What is a Network Protocol?

• A communications mechanism
• Many flavors
• IPX/SPX
• OSPF
• Big two
• UDP
• Connectionless
• TCP/IP

5
Internet TCP/IP

• Connection oriented
• End to end mechanism
• Networking layer
• Loaded
• Protocol suite
• Router configuration
• End user configuration

6
Internet Protocol Version 4

• Fast
• Scalable
• Problems
• Complexity
• Addressing Scheme
• (demo addressing)

7
Problem

• Finite space
• 32 bits
• Class allocation schemes
• Problem scale (crisis?)

8
Solution - IPv6

• Grand allocation schemes
• New technologies
• Neighbor identification
• QoS
• Reduced Complexity
• Scalability
• Maturity

9
Version Comparison

• IPv4 IPv6

Does it affect you?

• Installation
• Transparency
• Research
• Test beds
• Transition technologies

12
Transitioning mechanisms

• 6 to 4
• 4 to 6
• DTTS
• Expensive

13
Review

• Protocols run computer communication
• IPv4 has problems
• IPv6 will gradually replace
• Transitioning mechanisms will make nearly
  transparent
• Potential problem
• YOU might need to address problem.
